Abstract/Contents: | "Crop cultivation and turfgrass management are presently facing many challenges due to soil salinization. The major contributor to soil salinization is Sodium chloride (NaCl). Crop plants encounter various physiological and biochemical alterations under salinity stress, which greatly reduces yield and productivity. Zoysiagrass is an important turfgrass species that is used widely in the US. Leaf firing is one of the most conspicuous symptoms in zoysiagrass under salinity stress, which leads to a drastic economic loss. An interspecific mapping population between tolerant Z. matrella acc. PI231146 and susceptible Zoysia japonica var. Meyer has been developed for the identification and mapping of Quantitative Trait Loci (QTL) related to salt tolerance. Around 200 F2 plants were screened under normal water and 30 dS/m levels of salinity. The mapping population along with their parents have been phenotyped with several morpho-physiological parameters such as chlorophyll content and FVFM. Plants showed a range of phenotypic responses from extreme susceptibility to a high tolerance. DNA libraries of individual genotypes are ready to be sent for genotyping by GBS to find out significant SNPs, followed by an association between phenotype and genotype to identify and map major QTL. Future work includes repetition of the trial and analysis of differentially expressed genes between salt tolerant and susceptible genotypes through the Bulk Segregant RNA sequencing approach. This study is expected to provide key information regarding salt tolerance in zoysiagrass which will guide the upcoming zoysiagrass improvement projects." |
